\caption{Comparison of energies across deployment strategies:
unsigned differences in potential energy ($U$), kinetic energy ($K$), and
Hamiltonian ($H$) relative to the baseline simulation over 100 time-steps.
The number in each subfigure indicates the deployment method
as defined in Table~\ref{tb:deploy8}.}\label{fig:convergence}
